Sleep

Eight broken hours aren’t eight good ones.

Shipshape reads your night from Apple Health and scores it on how consolidated it actually was, not just how long you were lying there.

The problem with totals

Most health apps ignore sleep structure.

Eight hours broken into a dozen pieces adds up identically to eight consolidated ones. Only one of them leaves you rested, so Shipshape keeps the whole timeline, not just the totals.

What gets measured

Seven things beyond the hours.

MeasureWhat it means
Onset latencyHow long from getting into bed to properly falling asleep
Wake after onsetTime awake between first falling asleep and finally getting up
AwakeningsWakes longer than five minutes — the standard unit
Effective sleepSleep in stretches long enough to count as restorative
Restless timeSleep discarded for arriving in fragments too short to help
Longest boutYour single longest unbroken stretch
DensityHow much of the night's span you were genuinely asleep for

If nothing on your wrist recorded when you got into bed, onset latency is unknowable — so it is left out of the score rather than counted as zero. Guessing would quietly punish you for your watch's gaps.
